i got a question about this, how do i get the pipes far enough apart to pull off, but close enough to seal? never had a 2-1.

mine is off an old toyota.

Check any muffler shop in your town. I scored a Y shaped collector piece from a Midas, 10 bucks.

Or the junkyard with a battery operated sawzall. And imagination.

If I catch you right, you mean how close the ends had to sit to the engine?
depends on which motor you have!
I've made me a 2in1 exhaust for my ironhead. on this one, the exhaust sits just as close as the normal exhaust and you can easyly pull it off!

and to the question where to get a collector. just buy yourself a normal exhaust from a honda, yam ..... on ebay and then cut the collector off. and before that, ask the seller about the diameter of his exhaust.

I made my head pipes a slip fit into the collector.

Burns Stainless makes some of the best collectors out there- and not all of them are stainless.

I just bought a bagger Thunderheader with crushed headpipes off of E-bay for way cheap and got to welding up a set of pipes for my Shovel. Probably have $250 in the whole thing including the wrap to cover my fugly flux-core wirefeed welds (hey, it's all I've got at the moment).

I like that the best (slipfit) with tabs welded on for collector retention springs like a dirt bike! Hey since the motor vibrates at a different frequency than the frame, should I rubber mount the collector so I don't bust the exhaust studs?

Speedway Motors has the least expensive cone I've found (making a set myself) and I'm going to put a joint on the back pipe before it enters the cone with a mating joint made with two bolt-together exhaust flanges. Maybe not the best setup, but I think it looks cool...

What about this...



$60 It's cheap enough that you could chop it up and use how you want.

Used a set of drag pipes and a 3" truck turnout. Added 1" of pipe to the down section of the rear pipe from the back section I cut off. Cut slice and roll around the drag pipes. Weld solid and paint with engine paint. Used drag pipe, free. Turnout 39 dollars. time about 4 hours.
